Maybe a Casita or similar?
You might think about restoring an older smaller Airstream (if you can find one) and join those who have found a long term hobby. Of course, it will be a while before you get it camping again. Hmmm. Just a thought.

I find that the Minuet is a nice size that tows well with my Tacoma. It weighs about 3300# when I get ready to go - pretty close to what the Caravel is supposed to weigh.

I hate to admit it, but I just have too many projects going and I want to spend more time camping rather than fixing. So yesterday we picked up a 21' Bigfoot trailer. It needs tires/wheels and some polish along with re-sealing the seams on the roof vents. Other than that it is ready to go, so out with the cool gleam of aluminum and in with the shine of fiberglass!
